Sudden screen flickering with lines

[AyushiNM]

Hey. My laptop screen started flickering all of a sudden. I have no idea why this is happening and it hasn't happened before.

Everything is working fine, the system is booting up properly. It's just the screen that's shaking.

Please help me understand the issue and let me know how I can fix this?

And if I can not fix it, how much charges should I expect from a hardware shop to fix it?

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• When was the last time it worked without these issues?
• Have you updated Graphics and Chipset drivers?
• Have you checked the display on an external monitor?

Let’s try these steps to resolve the problem:

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 

If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure.

Hope this helps! Keep me posted for further assistance.
